Schmidt & Bender dial up turrets

Has anyone out there converted or made a dial up type turret for a S&B Klassik model?

I have several S&B's which I would like to have the ability to be able to dial up if nessacery. I have taken the elevation turret protector off and thought about puting a white self adhesive label on top. There is a mark on the main tube which you could reference from and I thought I could then make marks on the adhesive label say to include 300, 350 etc etc
